sorted¶
If elements in a List implements the Comparable interface,
you can call the method sorted to return a sorted List (in nature order).
Note: Pair in Kotin does not implement the Comparable interface!!!
Returns and Jumps in Kotlin
Break at label is a convenient way to jump out of a nested loop.
Arrays in Java
Comments¶
- An array in Java is not an
Iterable(due to design reasons). There is no super class of array andIterableeither in Java. If you want a method to support both array andIterableas the parameter, you need to overload it (for both array andIterable.) It is the same situation in Kotlin as Kotlin is mostly Java.
